9 of 35 tracked models do.
Article 53 of the EU AI Act requires providers of general-purpose AI models to publish a summary of their training content. California's AB 2013 asks a similar question of the same companies.
Article 53 of the EU AI Act and California's AB 2013 both require providers to publish what their models were trained on. What that means.
Two deadlines apply. Models on the EU market from 2 August 2025 had to comply at once; those already on sale have until 2 August 2027. For most models no provider states a placement date at all, so “not published” is not the same as late — see the breakdown below. What Article 53 requires · how this is compiled.
35 models tracked · 9 have published a training-data summary · every claim dated and linked to its source

No models match that filter.
Which of the two Article 53 deadlines applies decides whether an empty cell means late or not yet due.
Obliged from release
Placed on the market after the cutoff.
Have until 2027
On sale before the cutoff, so nothing is owed yet — 335 days until 2 August 2027.
Cannot be determined
The provider does not state when the model was placed on the market.
One model is past the cutoff with no summary found
Reconstructed from the commit history — one point per day the register was re-checked. This tracks our verification, not vendor behaviour: no provider published anything new in this window.

Providers with more than one model on the register. Disclosure is recorded per model because the same company often publishes for one and not another — a provider-level row would be true and false at once.
2 of 4 multi-model providers have no confirmed summary on this register
Share of tracked models where the document actually exists. The spread is the finding: the cheap, factual duties are met; the ones that require disclosing training content are not.
